The Law Of Sines:
For any triangle with sides a,b, and c.
Sin A = Sin B = Sin C
a b c
to find the side of a triangle-c^2= a^2 +b^2=2abCos(x)
to find the angle of a triangle-CosC=c^2- a^2-b^2 divided by -2ab

Inscribed angle: an angle whose vertex lies on the circle and whose sides are chords of the circle.

Inscribed Angle Theorem 9.3.1: The measure of an inscribed in a circle is equal to one-half the measure of the intercepted arc.

An acute triangle is a triangle with three angles less than 90 degrees.

An obtuse triangle is a triangle where one angle is more than 90 degrees but less than 180 degrees.

A right triangle is where one angle is 90 degrees.
